Boston Bruins defenseman Zdeno Chara smiles during Tuesday news conference leading up to tonight’s Game 1 of his team’s Stanley Cup Finals series.

CHICAGO — Zdeno Chara would just as soon steer the conversation from his size. It’s not hard to do, considering his contributions are as big as his frame.

“I’d rather have the talk about my game rather than just my size,” the 6-foot-9 defenseman said.

Chara is one of the main reasons — a big reason? — the Boston Bruins are back in the Stanley Cup finals, aiming for their second title in three years. They face off against the Chicago Blackhawks in Game 1 on Wednesday, the first time Original Six franchises are meeting for the championship since 1979.

The big, bad Bruins allowed just two goals while sweeping high-scoring Pittsburgh in the Eastern Conference semifinals with Chara playing a major role. Now, they’re set to face a team that dominated like no other during the regular season, getting off to a record-setting start and capturing the President’s Trophy in the end.

“They’re very skilled, fast, have a lot of depth on their team,” Chara said.

In some ways, the Blackhawks remind him of Pittsburgh, and the Penguins didn’t fare too well against Boston.

Former MVPs Sidney Crosby and Evgeni Malkin for Pittsburgh in the conference finals didn’t even register points in the conference finals.

Now, Patrick Kane and Jonathan Toews will try their luck against the Bruins.

No team has been stingier than Boston in the postseason.

The Bruins have allowed just 30 goals in 16 games for a league-best 1.88 average in the playoffs after finishing third behind Chicago and Ottawa during the regular season, and they just shut down a team that led the league in goals.
